CHARLES A. CARMANY, OF COATESVILLE, PENNSYLVANIA.

SHADE-ROLLER.

Application filed May 29, 1914.

To all whom it may concern Be it known that 1, CHARLES A. CARMANY, a citizen of the United States, residing in Coatesville, Chester county, State of Pennsylvania, have invented certain Improvements in Shade-Rollers of which the following is a specification.

My invention consists of improvements in adjustable shade rollers and particularly those made in a numb-er of telescopic sections.

One object of the invention is to provide a durable and comparatively inexpensive shade roller of such construction that ashade may be quickly and securely attached thereto, it being also desired to provide novel means for insuring the positive locking of the roller in a desired position.

The invention also contemplates novel means for preventing the roller from moving out of its bearing while being rotated.

These and other objects which will be mentioned hereinafter I attain as hereinafter set forth, reference being had to the accompanying drawings, in which,

Figure 1 is a longitudinal section of my improved shade roller; Fig. 2 is a vertical section on the line aa, Fig. 1; Fig 3 is a sectional elevation of the left-hand end of the roller, taken on the line bb, Fig. 1; Fig. 4 is an elevation of the right-hand end of the roller; Fig. 5 is a transverse section on the line c0, Fig. 1; Fig 6 is a fragmentary perspective view of my improved form of shade holding strip; Figs. 7 and 8 are elevations showing the bearing members for the opposite ends of the roller which is shown as mounted in said bearings; and Fig. 9 is a perspective view of one of the elements of the invention.

The roller illustrated in the accompanying drawings is of the same general type as that shown in my Patents No. 1,013,531 and No. 1,013,532, January 2, 1912, and is made up of two hollow telescoping sections 1 and 2, grooved or slotted at 3 and 4 respectively; the groove of the inner section being spanned by a bent metal plate 5. This forms a housing for folded metallic shade holding strips 6 and. 7 which may be introduced through an openingS in an end cap 9 secured in one end of the roller. These shade holding strips, which are preferably made out of sheet metal, have folds 10 and 11, and the end 12 of the fold 10 projects beyond the end 13 of the fold 11, as shown in Specification of Letters Patent.

Serial No. 841,952.

Fig. 6, the corners 1a and 15 of said parts being rounded. The body portion of the strip has a tongue 16 projecting beyond both of the ends 12 and 13.

A plate 17 is fitted into the end of the roller opposite that having the cap 9 and to prevent it from rotating therein 1 turn in the edges 18 of the slot 3, which enter a recess 19 of said plate. This latter forms a bearing for abar 20 which has one end attached to a torsion spring 21 whose opposite end is secured to the rear face of said plate. This latter has recesses formed in its outer face serving as retainers for clutch balls 24 and 25 and they are formed with rounded portions 26 and 27 constituting pockets for the reception of said balls. The edges 28 and 29 of these recesses extend practically tangent to one side of each of these pockets, while the other edges 30 and 31 extend so as to intersect said walls. A pawl plate 32 is secured to theend of the rod 20 and at op posite points 33 and 34; its edges are recessed for engagement with the clutch balls; the arrangement being such that relative movement in one direction between the pawl plate 32 and the plate 17 will result in said balls being caught between the recessed edge of the first of these plates and a shoulder 35 or 36 of the pockets in the plate 17, thus locking these parts together. On the other hand, relative movement of the two plates in into the groove formed by the turned in edges 18 of the section 1.

Within that end of the roller section 2 dis tant from the plates 17 and 32 I mount a bearing structure 39 in the form of a plate having its top edge 42 curved to fit the innercurved surface of said section, and having its bottom edge 11 straight to rest upon the inner face of the strip 5. Said bearing structure has resilient wings 10 projecting, at right angles and engaging the walls of the section 2 so as to prevent said structure from vibrating or getting out of place. This structure has a flange opening 38 as shown in Fig. 9 for the reception of the inner end 37 of the rod 20 and in order to retain said bearing structure from movement out of the roller section, the plate 5 is provided with a projecting tongue 5" engaging this part 39 as shown in Fig. 1.

The journal end lt of the roller is rectangular in section and fits within a rectangular slot 45 in a bearing member or support 4L6; there being a passage 47 leading thereto which allows the insertion of said end. The opposite end of the second roller section 2 has the cap 9 provided with a flanged cylindrical journal L8 rotatably mounted in a second bearing member or support 50. The slot 51 in this support 50, in which the journal 48 rotates, extends upwardly and inwardly toward its entrance at an incline to the wall or other vertical support to which said support is secured with the result that the roller will be retained in place against a tendency to jump or ride out of its bearings when it is rotated to wind-up the shade. This is an important feature of my invention for hitherto much annoyance has been caused by the rollers with their shades getting out of the supporting bearings when these had slots which extended vertically or at an incline outwardly from the wall.

By constructing the shade holding strips in the manner above noted, the folded edge of the shade can be inserted more easily and quickly than was heretofore possible where the edges of the strip folds were even. In :assembling the shade and roller the end 12 of the extended flap 10 forms a bearing for the folded edge of the shade which may be fully passed between it and the tongue 16, of the body portion, as shown in Fig. 6. After the end portion of the folded shade has been started between these parts its body portion may be easily guided through the folds 10 and 11. Any number of folded strips may be employed (two being shown in the accompanying drawings), and under conditions of use the tongue 16 of one strip may be used as a coupling means by projecting it between the folds of an ad acent strip, as shown in Fig. 2. This tongue also serves as a guiding means when the strips are being inserted through the opening 8 into the roller. The rollers are preferably made out of sheet metal but it will be understood that the features of my invention may be used advantageously in rollers made of other material and of different construction.

I claim 1. The combination of a shade roller; and

a folded shade-holding strip therein, the end of one of the folds of said strip projecting beyond the end of another to provide guiding means for a shade.

2. The combination of a shade roller; and a folded shade-holding strip, the end of one of the folds of said strip projecting beyond the end of another to provide guiding means for a shade, the corners of said ends being rounded to allow of the free passage of the shade thereover.

3. The combination of a grooved shade roller; and a folded shade-holding strip having a tongue projecting from one end for guiding said strip into the groove of said roller.

a. The combination of a grooved shade roller; and a plurality of folded shade-holding strips, each having a tongue projecting therefrom, the tongue of one of said strips being arranged to extend into another of the said strips to couple the same.

5. The combination of a grooved shade roller; and a plurality of folded shade-holding strips, each having a projecting tongue, the tongue of one of said strips being arranged to extend between the folds of another.

6. The combination in a shade roller of a body portion; a clutch ball; a plate secured to said body portion and having a cavity including a curved pocket for said ball; and a member movable relatively to said plate into engagement with the ball for confining it within said pocket and thereby stopping relative movement of the plate and member, one wall of said cavity intersecting the wall of said pocket to form a shoulder, and another wall of the cavity being plane and extending at a tangent to said pocket wall.

7 The combination in a shade roller of a body portion; a clutch ball; a plate secured to said body portion and having a cavity including a curved pocket for said ball; and a member movable relatively to said plate into engagement with the ball for confining the latter within the pocket and thereby stopping relative movement of the plate and member; the walls of said cavity diverging from the walls of said pocket, one wall of the cavity intersecting the pocket wall to form a shoulder, and another wall of said cavity being plane and extending at a tangent to the wall of the pocket.

8. The combination in a shade roller of a body portion; a plate secured thereto having cavities, each including a curved pocket; clutch balls respectively movable in said pockets; one wall of each of said cavities intersecting the wall of its pocket to form a shoulder, another wall of each of said cavities being plane and extending at a tangent to its pocket wall; with a member movable relatively to the plate in one direction to move the balls into contact with the shouldered portions of their pockets and movable in the opposite direction to move the balls out of the pockets into contact with said tangent walls.

9. The combination of a hollow grooved shade roller; a member within said roller spanning the groove thereof; a rod in said e roller; means for supporting said rod at its outer end; and a bearing plate having a hole forming a bearing for the opposite end of said rod, said bearing plate having one edge coincident and in engagement with said spanning memberthe opposite edge of the plate being shaped to fit the inner surface of the roller.

10. The combination of a hollow grooved shade roller; a member Within said roller spanning the groove thereof; a rod in the roller; means for supporting said rod atits outer end; a bearing plate having a hole forming a bearing for the opposite end of said rod, said bearing plate having one edge coincident and in engagement with said spanning member, the opposite edge of the plate being shaped to fit the inner surface of the roller; with resilient wings projecting from said bearing plate and in frictional engagement with the inner wall of the roller.

end; a bearing plate having a hole for the opposite end of said rod, said bearing plate having one edge resting on said spanning member and its opposite edge shaped to fit the inner surface of the roller; and a projection on said spanning member forming a stop to prevent longitudinal movement of the bearing plate within the roller toward said latter end of the rod.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
